柏金遜症是全球第二普及的神經系統疾病,預計到2030年將有超過870萬名患者,醫學界現時會利用深腦刺激手術(DBS)等方式,嘗試瞄準頭顱特定微小範圍的腦細胞診治。香港大學科研團隊成功開發出一套神經外科機器人系統,首創能於磁力共振掃描器(MRI)頭部線圈內作立體定位,在不受磁場影響下,可確保手術能更準確、更安全、更有效地進行,造福大批柏金遜症及其他相關腦部疾病病人。

團隊由港大工程學院助理教授郭嘉威帶領,而中文大學外科學系腦外科組專家亦有參與臨床驗證,有關機器人系統近日於國際電機電子工程師學會(IEEE)的「2018國際機器人與自動化會議」獲頒最佳會議論文獎。

實時監察免腦「走位」

團隊介紹指,深腦刺激手術與心臟起搏器相似,透過植入電極,將電訊號傳送至大腦深部的指定範圍,講求極高精準度,可幫助恢復神經細胞正常活動,同時避免損害周圍腦部組織。

不過,現有手術只能於術前瞄準及定位,欠缺實時監察,醫生為病人顱骨穿孔後,可能令大腦組織變形和移位,大大降低定位準確度。因此,該手術一般只會為病人作局部麻醉,讓其在開腦的同時保持清醒,醫生透過與其對話互動,確保放置電極的過程無誤。

開腦終可全身麻醉

團隊開發的神經外科機器人系統便是針對有關情況開發。他們棄用了常見的電磁摩打,為機器人設計出液壓驅動的遠程操作系統,能與帶有強大磁場的MRI兼容而互不干擾。透過新系統,病人可以全身麻醉,並用微創方式在左右兩邊腦部放入儀器,醫生則可以邊進行手術,邊以MRI掃描成像,即時準確掌握施術位置。

研究團隊並設計了可以對左右大腦同時施精準手術的機械手臂,同時開發了先進的三維追踪標記,可以助機器人系統在MRI中實時、快速地定位,令腦部手術朝向更安全、更準確和更有效的方向邁出重要一步。

除了應用於腦外科外,研究團隊指機器人系統的核心技術,亦可望應用於其他MRI導航手術,例如心臟導管術、前列腺或乳房組織切片檢查等,下一步會開展更多臨床研究,以確定系統於相關領域的功效。
